Hi all,

I bought a Bluetooth OBD2 unit the other day. Seems quite a good bit of kit for £10.

So far I have connected to a 2003 Saab 9-3, my MK1 Octy & a 2007 Seat Altea.

There are lots of PC based software, but being a Nokia user (they are 'smart phones' don't you know) I have been using OBDSCOPE

The programs are not a patch on VAGCOM, but they allow you to monitor various parameters and look at fault codes.

Now, where is the girlfriends OBD2 port!

I've had one of these ELM/Bluetooth gadgets for about a year and they're great so long as you have the right software. I tried OBDSCOPE on my N95 and it was okay, but I use an iPaq PDA running OBDGAUGE which is open source (i.e. free) and does everything I need. It can also run on a Palm and can download collected data to a companion PC program.

The only problem I've had with mine was when using some Linux PC open-source software designed for a wired connection on serial port 1 or 2. Bluetooth serial (RFCOMM) connections are always somewhere up above port 16 or something. Anyway I tracked down a port mapper program that allowed me to map the Bluetooth connection to port 2 and it worked after a fashion, but it was fiddly getting it set up.
